Convert the notifiers to state machine states and let the core code do the

ordering requirement versus perf hardcoded in the notifier priority. This
odering is only required for CPU down, so that hardware migration happens
before the core is notified about the outgoing CPU.

perf/core: Convert to hotplug state machine
...
Actually a nice symmetric startup/teardown pair which fits properly into
the state machine concept. In the long run we should be able to invoke
the startup callback for the boot CPU via the state machine and get
rid of the init function which invokes it on the boot CPU.
Note: This comes actually before the perf hardware callbacks. In the notifier
model the hardware callbacks have a higher priority than the core
callback. But that's solely for CPU offline so that hardware migration of
events happens before the core is notified about the outgoing CPU.
With the symetric state array model we have the following ordering:
UP: core -> hardware
DOWN: hardware -> core

More or less straightforward, although this driver sports some very

That comment is half baken as the same requirement is true for perf.

cpu/hotplug: Handle early registration gracefully
...
We switched the hotplug machinery to smpboot threads. Early registration of
hotplug callbacks, i.e. from do_pre_smp_initcalls(), happens before the
threads are initialized. Instead of moving the thread init, we simply handle
it in the hotplug code itself and invoke the function directly.
